PLATE-MARKING- DEVICE.

Application filed May 26,

7 '0 all whom it may concern:

Be it known that I, EDWARD I-I. WALSH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Plate-Marking 'Device, of which the following is a specification.

My invention relates to a device for marking-plates as they pass along upon a carrier of any kind, and particularly to apparatus for use in connection with rotary shears used for trimming the edges of plates as they pass through the shears.

In rolling operations it is frequently desirable to roll the sheets into wide strips and then cut'the strips longitudinally into Prior to running the sheets through the shears for cutting the narrowerstrips it is necessary to: mark the sheets to guide the operator so that the sheets will be cut .to the proper width. Heretofore in doing this kind of work it has been necessary to lay out the lines on the sheets by hand before they pass to the shears and has necessitated an extra amount of work and also because the operation is done by hand it is sometimes not accurate and results in a waste of material. By my improved invention as the sheets are passed through the shears for trimming the edges the plate is marked by my device with a line extending longitudinally thereof and which is easily followed by the operator of the shears which cuts up the sheets into narrower widths. It also enables the sheets to be moved along without delay to the shears and thus the strips are cut up without delay and without the necessary operation of marking, as heretofore explained.

, Another and further object of my invention is the provision of an apparatus for making sheets which is simple and efficient in operation and economical in results and which, when set by the operator, is substantially automatic in operation.

These and other objects of my invention will be more readily and better understood by reference to the accompanying drawings, and in which- Figure 1 is a cross-sectional view through a rotary shearing machine showing my apparatus secured thereto;

operator to place the device into contact with the sheets;

Figure 5 is a detail View of the apparatus showing the scale graduations thereon;

Figure 6 is an end elevational view of one of the marking devices; and

Figure 7 is a side view in elevation of the same device.-

Referring now specifically to the drawings, a fixed shear 10 is shown having a frame 11 which is secured to a track 12 by means of a bolt 13, only such portions of the shear 10 being shown as are necessary to illustrate my invention. A movable shear 14 is shown comprising a frame 15 which slides upon the track 12, the rotary shear blade of the movable shear 14 being raised or lowered by the hand wheel 16 to and from the shear 24:, in order to adjust the shear blades to various positions to accommodate sheets of varying thickness.

Referring to the fixed shear 10, a rotary shear blade 17 is shown which is mounted upon a shaft 18 extending into the frame 11 of the machine 10 and having at its opposite end any suitable driving mechanism, the shear blade 17 being raised or lowered by the hand wheel 16. Mounted upon the outer end of the shaft 18 is a guide roll 19 which is adapted to contact with the sheets on the upper side thereof and hold them as they pass the shearing machine and along the roller bed 28 which forms a conveying table over which the sheets pass. Secured to the frame 11 of the machine is a rotary shear blade 20 power driven in any suitable manner which is just outside of and underneath the rotary shear blade 17 and which contacts with the plate on its under side and forms a part of the shearing mechanism. The movable shear 14 is substantially like the shear just described and has an upper shear blade 21 mounted upon a shaft 22, driven in any suitable manner and a guide roll 23 on the outer end of the shaft 22. The removable shear 14 is mounted upon and moves along the rail 12 toward and away from the fixed shear 10, this movement bei g accom lished by a worm gear 15 which engages with a stationary rack (not shown) A rotary Shear blade 24 is mounted upon the frame of the machinand serves to hold the material in position-under ing power driven in any suitableinanne'rb A plate 25 is shown passing through the shears and having marginal strips 26 27 cut off its sides as it passes through the shears upon the roller bed' 28 and being supported by a pair of longitudinally extending members '28 positioned between the sheerblades. seem-ed to the frame 11 in any suitable manner is a bracket 30, a similar bracket 31 being secured to the fr ame 15 of the movable shear 14. A shaft 32- is mounted at each of its ends iii the brackets 30 and 31 respectively,- and extends from the fixed sheet- 10 to the movable shear 14. The said shaft 32' is round at its end 33 which is n'ioiint'ed on the fixed shear '10 and is square in cross=section for the-balance of its length. A bushing 29 isnibiiiited in the bracket 31 so that the shaft 32 will slide therethro'u'gli' when the" movable shear 14 is moved to accommodate sheets or different Widths. Secured to the shaft 32 is a pair of riiarkir'ig 'dei ic'e s 34 and 35, one of said devices being illustrated in detail in Figures 6 and '7, and each of the marking devices being movable longitudinally of the shaft 32. Each of the marking devices, and of which any number desired may be secured to the shaft 32, consists of a bracket 36, a cap 37 having projections 38 and 39 on each of its sides which fit against projections 40 and e1 integral with said bracket 36' and forming a part thereof, and having bolts 41* and 42 which pass through the projections 38 and 40, and 39 and 41 respectively, to hold the bracket 36 and the cap 37 in position around a bushing 42 which is placed upon the shaft 32. The bushing 42* has collar portions as and 4A on each of its ends, the bracket 36 and cap 37 fitting in betweeii the collar portions 4&3 and 44E of the bushihg 42*. A set screw 45 is inserted through the collar 43 on the bushing 42* and is in' frictional engag'ei'nent ith the shaft 32 so that the marking device may be set in any position at any point along the shaft 32 and held in position. The bracket 36 has a slightly projecting po'rtio'n l6 which is adapted to cb-act with a stud 47 in the collar' 44 of the bushing 42 when the marking device 34. is turned over and out of operative position. Secured to the br cket 36 by means of a pin 48 is a holder 49, the sahl holder being divided and having a marking element 50 inserted between the end portions of the holder 49,- thesa id marking element 50, such as soapstone or the like, is held in contact with the plate and makes a mark upon said plate longitudinally thereof as the plate passes through the shear. A thumb screVg 51 'serves to rel-amp the" member 49 upon the marker 50 so that itis-held securely in position to the holder 49. Secured' to oneend of the shaft 32 is a lever 52 which is connected to a handle 53,

the handles?) being carried by a member 54 which is secured to one side of the shear bed 283 The handle 53 passes through a slot in the member 54 and which has a projection 55 thereon which is adapted to ngage in notches 5'6- and 57 iiithe handle '53 In case it'isdesiredto lift-the ram-hers; eat of Contact With the plate 25 the ha 'nd le is pulled -back-War"d and the prejeetihh '55} en gages the'notch stand the ieterts andth s the market-e are held out of Contact 'wifihth'e plate, if it is desired to use only one market the other may heturheci byhaiid upon the bushing 42* until the pettien 4c of the bracket 36 engages the stud '47 so that it is out of ehh tatt with the piate as it isjp'as'sed between the shearing hreaes hha sihgle marker may be ei her 'Itinaybethat iii tli operatieh -=of-theshears-that plates win he passed therethrou-gh fc'ir trimming the edges or the shears withehtfiieuahg theni for cutting intoiilarr'dfwer'stri'psz The shaft 32'- is ee-hbrete'd as shewn' i'n' Figure 5, so that the meshing device'hlay head justed thei-eeh to difiereht positions oh the saidshaft and thereby mark the sheets into different Widths as they ass through the-shears.
